Based on capacitive touch sensing switch module, when the body is directly touching the metal or metal on the surface of the sensor, it can be sensed.
In addition to directly touch the outer metal surface, across a certain thickness of plastic, glass and other materials can also be sensed, the sensitivity of the sensor with the size and thickness of the cover material of the metal surface of a relationship.

• With foil stickers, can be easily affixed to the door glass or used in conjunction with Arduino sensor expansion board, you can create very interesting touch interactive works.
